Abstract

The OFDM system based on the fractional Fourier transform (FRFT-OFDM) is robust against fast-fading channel. However, the performance of anti-jamming is not analyzed. In this paper, the anti-jamming performance of the FRFT-OFDM system under multitone jamming (MTJ) and linear frequency modulated (LFM) jamming is evaluated. The evaluation is carried out by calculating bit error rate with probability density function. It is indicated from the theoretical analysis and simulation results that under MTJ and LFM jamming, the anti-jamming ability of the FRFT-OFDM system will be enhanced greatly by adjusting the system parameter, which is much stronger than that of the FFT-OFDM system.
